Cookie Policy
Cookie Policy
Effective Date: March 22, 2026 Last Updated: March 22, 2026
This Cookie Policy explains how Angola 2050 (“we,” “us,” or “our”), a publication of the Vanderbilt Portfolio, uses cookies and similar tracking technologies on angola2050.com (the “Site”). This policy provides comprehensive information about what cookies are, which cookies we use, why we use them, how they affect your privacy, and how you can control them. This policy should be read alongside our Privacy Policy and Terms of Service.
What Are Cookies
Cookies are small text files placed on your device (computer, smartphone, or tablet) by your web browser when you visit a website. Cookies are widely used across the internet to make websites work more efficiently, to improve user experience, to provide functionality that users expect, and to supply information to website operators about how their sites are being used. Cookies were invented in 1994 and have become a fundamental component of how the modern web operates.
Cookies serve a variety of purposes. Some are essential for a website to function at all — for example, cookies that maintain your session state as you navigate between pages, or cookies that remember your consent preferences so that you are not asked to re-consent on every page view. Other cookies are used to understand how visitors interact with a website, enabling the operator to improve the site based on actual usage data. Still other cookies are used to serve relevant advertising, which is the economic model that supports many free-to-access information resources on the internet, including Angola 2050.
Types of Cookies by Duration
Session cookies — These cookies are temporary and are deleted from your device when you close your web browser. They exist only for the duration of your browsing session and are typically used to maintain session state, such as keeping you logged in as you navigate between pages. Session cookies do not collect information from your device and do not identify you personally.
Persistent cookies — These cookies remain on your device for a set period of time (specified in the cookie’s expiration date) or until you manually delete them. Persistent cookies are activated each time you visit the website that created them. They are used for purposes that require data to persist across multiple browsing sessions, such as remembering your consent preferences, distinguishing returning visitors from new visitors in analytics data, or maintaining advertising frequency caps.
Types of Cookies by Origin
First-party cookies — These cookies are set by the website you are visiting (in this case, angola2050.com). They can only be read by the site that created them. First-party cookies are typically used for essential functionality and basic analytics.
Third-party cookies — These cookies are set by a domain other than the website you are visiting. On Angola 2050, third-party cookies are set by Google (for Analytics and AdSense services). Third-party cookies enable services that span across multiple websites, such as cross-site analytics and advertising networks.
Similar Technologies
In addition to cookies, websites may use similar tracking technologies including:
- Web beacons (also known as pixel tags or clear GIFs) — Small, transparent image files embedded in web pages or emails that track whether a page has been viewed or an email has been opened. Google Analytics and AdSense may use web beacons in conjunction with cookies.
- Local storage — A browser feature that allows websites to store data on your device with more capacity than cookies. We may use local storage for non-personal functional data such as display preferences.
- Session storage — Similar to local storage but automatically cleared when you close the browser tab. Used for temporary functional data within a single browsing session.
Cookie Categories We Use
Strictly Necessary Cookies
These cookies are essential for the Site to function properly. They enable core features such as page navigation, security, session management, and access to secure areas. The Site cannot function correctly without these cookies, and they are set automatically when you access the Site. They do not require your consent under applicable data protection laws, including the GDPR and the ePrivacy Directive, because they are necessary for the provision of the service you have requested.
Strictly necessary cookies do not collect information about your browsing behavior for marketing purposes and are not used to remember where you have been on the internet outside of our Site.
| Cookie | Purpose | Type | Duration | Data Stored |
|---|---|---|---|---|
| Session ID | Maintains your session state as you navigate between pages, ensuring that page requests are associated with the correct user session | First-party, session | Session (deleted when browser closes) | Randomly generated session identifier |
| Consent preferences | Stores your cookie consent choices so that you are not asked to re-consent on every page view and so that consent-dependent features (Analytics, AdSense) respect your preferences | First-party, persistent | 12 months | Consent status for each cookie category (granted/denied) |
| Security tokens | Prevents cross-site request forgery (CSRF) attacks by validating that form submissions and state-changing requests originate from the legitimate Site rather than a malicious third party | First-party, session | Session | Cryptographic token |
| Load balancer affinity | Ensures that subsequent requests during your session are routed to the same server, maintaining consistent session state and optimal performance | First-party, session | Session | Server identifier |
Analytics Cookies
We use Google Analytics 4 (GA4) to understand how visitors interact with the Site. Analytics data helps us identify which content is most valuable to our audience, which pages have high bounce rates (indicating potential quality or relevance issues), which traffic sources drive the most engaged visitors, and how users navigate through the Site. This data directly informs editorial decisions about content production, site navigation improvements, and resource allocation across our six coverage verticals.
Analytics cookies are only activated after you provide affirmative consent through our consent management platform. If you do not consent to analytics cookies, Google Analytics will not set cookies on your device and will not collect user-level data about your browsing behavior. In this case, we receive only aggregate, non-identifying signals through Google Consent Mode v2 (see below), which do not track individual users.
| Cookie | Purpose | Type | Duration | Data Stored |
|---|---|---|---|---|
_ga | Distinguishes unique users by assigning a randomly generated number as a client identifier. This cookie does not contain any personally identifiable information. | Third-party (Google), persistent | 2 years | Randomly generated client ID, timestamp of first visit |
_ga_[ID] | Maintains session state for Google Analytics 4, tracking session duration and the sequence of pages viewed within a single session | Third-party (Google), persistent | 2 years | Session ID, session count, timestamp |
Data collected by Google Analytics on this Site includes: Pages viewed, time spent on each page, scrolling depth, outbound link clicks, file downloads, session duration, number of sessions, new versus returning visitor status, traffic source (search engine, direct, referral, social media), browser type and version, operating system, device category (desktop, mobile, tablet), screen resolution, and country-level geographic location derived from IP address.
Data NOT collected by Google Analytics on this Site: We have disabled User-ID tracking, Google Signals, and advertising features within GA4. We do not create cross-session user profiles, do not track users across devices, and do not use Analytics data for remarketing or audience targeting. IP addresses are anonymized within Google’s collection network before storage.
For more details on Google Analytics cookies and data processing, see Google’s cookie usage documentation and Google’s data processing terms. You can opt out of Google Analytics entirely by installing the Google Analytics Opt-Out Browser Add-on, which is available for Chrome, Firefox, Safari, Edge, and Opera.
Advertising Cookies
We use Google AdSense to serve advertisements on the Site. Advertising revenue is the primary economic model that supports the continued operation of Angola 2050 and the production of free, publicly accessible intelligence content about Angola’s economy, energy sector, infrastructure, investment climate, and social indicators. Without advertising revenue, the Site could not provide the depth and breadth of coverage that our audience expects.
Google AdSense may set cookies to serve ads, measure advertising effectiveness, limit the number of times you see a particular advertisement (frequency capping), and combat advertising fraud and abuse. The behavior of advertising cookies depends on your consent status:
With personalized advertising consent: Google may use data about your browsing history across its advertising network to serve advertisements that are more relevant to your interests. This involves cookies that track your interactions with ads across multiple websites that participate in Google’s advertising ecosystem.
Without personalized advertising consent (default): Only non-personalized, contextually relevant ads are displayed. These ads are selected based solely on the content of the page you are viewing — for example, an article about Angola’s oil sector might display an ad for an energy industry publication or a financial services provider. Non-personalized ads still use cookies for essential advertising functions including frequency capping (preventing you from seeing the same ad repeatedly), aggregate reporting (measuring how many times an ad was displayed and clicked), and fraud prevention.
| Cookie | Purpose | Type | Duration | Data Stored |
|---|---|---|---|---|
__gads | Serves ads and measures ad interactions including impressions, clicks, and conversions | Third-party (Google), persistent | 13 months | Ad serving data, interaction metrics |
__gpi | Serves ads across Google services and measures cross-service ad performance | Third-party (Google), persistent | 13 months | Publisher-provided identifier |
NID | Stores preferences and information for Google Ads, including preferred language, number of search results per page, and whether Google SafeSearch is enabled | Third-party (Google), persistent | 6 months | Preference data, unique identifier |
CONSENT | Stores consent state for Google services, recording whether and when you consented to personalized advertising | Third-party (Google), persistent | 2 years | Consent status, timestamp |
IDE | Used by Google DoubleClick for personalized advertising to store information about how you use the advertiser’s website. Present only when personalized advertising consent has been granted. | Third-party (Google), persistent | 13 months | Ad interaction data |
ANID | Used by Google for advertising purposes to link your advertising activity with other Google services. Present only when personalized advertising consent has been granted. | Third-party (Google), persistent | 13 months | Advertising identifier |

Functionality Cookies
These cookies enable enhanced functionality and personalization, such as remembering display preferences, language selections, or the region you are in. They may be set by us or by third-party providers whose services we integrate on our pages. If you do not allow these cookies, some or all of these enhanced features may not function properly, but the core informational content of the Site will remain accessible.
| Cookie | Purpose | Type | Duration |
|---|---|---|---|
| Language preference | Remembers your preferred language setting if multilingual content is available | First-party, persistent | 12 months |
| Display preferences | Stores visual preferences such as font size or contrast settings if such features are implemented | First-party, persistent | 12 months |
| Dismissed notices | Records which informational banners or notices you have dismissed to prevent them from reappearing | First-party, persistent | 6 months |
Consent Management
Angola 2050 implements a consent management platform (CMP) that displays a cookie consent banner when you first visit the Site. The CMP is designed to comply with the GDPR, the ePrivacy Directive (Directive 2002/58/EC as amended by Directive 2009/136/EC), the Swiss Federal Act on Data Protection (nDSG), and the requirements of the IAB Transparency and Consent Framework v2.2.
The consent management platform provides the following options:
Accept all cookies — Enables all cookie categories including strictly necessary, analytics, advertising, and functionality cookies. By accepting all cookies, you consent to data collection by Google Analytics and the serving of personalized advertisements through Google AdSense.
Reject non-essential cookies — Only strictly necessary cookies are activated. Analytics and advertising cookies are not set, and Google tags operate in restricted mode through Consent Mode v2. You will still see advertisements on the Site, but they will be non-personalized and contextually targeted based on page content rather than your browsing history.
Customize preferences — Choose which specific cookie categories to enable or disable. You can consent to analytics cookies while rejecting advertising cookies, or vice versa. This granular control allows you to balance your privacy preferences with your desired browsing experience.
Withdraw consent at any time — You may change your cookie preferences at any time by accessing the consent settings through the consent management link in the Site footer. When you withdraw consent for a cookie category, existing cookies in that category are not automatically deleted from your device (this is a browser-level function), but the associated tracking scripts are immediately deactivated and no new data is collected. You should clear the relevant cookies from your browser if you wish to remove them immediately.
Your consent choices are stored in a first-party cookie on your device for 12 months. After 12 months, or if you clear your cookies, the consent banner will reappear and you will be asked to make your choices again. This ensures that your consent remains current and informed.
We implement Google Consent Mode v2 to ensure that Google tags (Analytics, AdSense) technically respect your consent choices in real time. When consent for a cookie category is denied, the corresponding Google tags operate in a restricted mode that does not set cookies and does not collect user-identifying data. For a detailed explanation of Consent Mode v2 signals, see our Privacy Policy.
Third-Party Cookies
Some cookies on the Site are set by third parties, not by Angola 2050 directly. We do not control these third-party cookies and are not responsible for their content, purpose, or data processing practices. Third-party cookies are set within the parameters defined by our consent management framework — non-essential third-party cookies are only activated after you provide consent.
We recommend reviewing the privacy and cookie policies of the following third parties to understand how they process data collected through cookies on our Site:
- Google (Analytics, AdSense, Consent Mode): Google Privacy Policy | How Google uses cookies | Google Ad Settings
- YouTube (if embedded videos are present on specific content pages): YouTube Privacy Policy | YouTube uses cookies to track video playback, remember player preferences, and measure engagement with embedded video content
We regularly review the third-party services integrated on the Site to ensure that their cookie practices align with our privacy commitments and applicable law. If a third-party service changes its cookie practices in a way that materially affects user privacy, we will evaluate whether to continue the integration and update this policy accordingly.
Managing Cookies in Your Browser
In addition to our consent management platform, you can control cookies through your browser settings. Every major web browser provides mechanisms to view, delete, and control cookies. Most browsers allow you to:
- View which cookies are stored on your device — Inspect the cookies set by specific websites, including their names, values, domains, expiration dates, and other attributes
- Delete individual cookies or all cookies — Remove specific cookies or clear all stored cookies from your device
- Block cookies from specific websites or all websites — Prevent certain domains or all domains from setting cookies on your device
- Set preferences for first-party versus third-party cookies — Allow first-party cookies while blocking third-party cookies, which would prevent Google Analytics and AdSense cookies while allowing our essential first-party cookies
- Configure cookie notifications — Set your browser to alert you each time a cookie is being set, allowing you to accept or reject cookies on a case-by-case basis
Please note that blocking all cookies, or blocking all third-party cookies, may impact the functionality of the Site and many other websites you visit. Essential features that rely on cookies (such as remembering your consent preferences) may not work correctly if cookies are completely disabled.
For instructions on managing cookies in the most commonly used browsers, see the following resources:
- Google Chrome: Manage cookies in Chrome — Chrome provides granular cookie controls including the ability to block third-party cookies while allowing first-party cookies, and to create exceptions for specific sites.
- Mozilla Firefox: Cookies in Firefox — Firefox offers Enhanced Tracking Protection with three preset levels (Standard, Strict, Custom) that automatically block known tracking cookies.
- Apple Safari: Manage cookies in Safari — Safari implements Intelligent Tracking Prevention (ITP) which automatically limits the capabilities of third-party cookies and cross-site tracking.
- Microsoft Edge: Manage cookies in Edge — Edge provides tracking prevention with Basic, Balanced, and Strict levels, similar to Firefox’s Enhanced Tracking Protection.
- Opera: Manage cookies in Opera — Opera provides cookie management options similar to Chrome, including the ability to block all cookies, block only third-party cookies, or allow all cookies.
If you use multiple browsers or devices, you will need to configure cookie settings separately for each one. Cookie preferences set in one browser do not apply to other browsers on the same device or to the same browser on a different device.
Do Not Track and Global Privacy Control
Some browsers offer a “Do Not Track” (DNT) signal that is sent as an HTTP header with each web request. DNT was proposed as a universal mechanism for users to communicate their tracking preferences to websites. However, there is currently no industry standard for how websites should respond to DNT signals, and the World Wide Web Consortium (W3C) retired its DNT specification in 2019 due to insufficient adoption. We do not currently alter our data collection practices in response to DNT signals.
However, we do honor consent choices made through our consent management platform, which provides equivalent (and more granular) control over tracking technologies. Additionally, we recognize the Global Privacy Control (GPC) signal, which is supported by certain browsers and browser extensions and is recognized under the CCPA/CPRA as a valid opt-out of the sale or sharing of personal information. When a GPC signal is detected, we treat it as a request to disable personalized advertising.
Cookies and Children
Angola 2050 is not directed at children under the age of 16, and we do not knowingly set cookies for the purpose of tracking children. Our consent management platform requires affirmative action to enable non-essential cookies, which provides an additional layer of protection for younger users who may access the Site. For more information about our practices regarding children’s data, see Section 13 of our Privacy Policy.
Cookie Auditing and Review
We conduct periodic audits of the cookies present on the Site to ensure that this Cookie Policy remains accurate and current. Cookie audits verify that only the cookies described in this policy are being set, that cookie durations match what is documented, that third-party cookies align with our integrations, and that our consent management platform correctly controls non-essential cookies based on user preferences. If we identify discrepancies during an audit, we take corrective action and update this policy as needed.
Changes to This Policy
We may update this Cookie Policy from time to time to reflect changes in the cookies we use, changes to our third-party integrations, updates to applicable law or regulatory guidance, or changes to browser technologies that affect how cookies function. When we make changes, we will update the “Last Updated” date at the top of this page. Material changes — such as the addition of new cookie categories, new third-party cookie providers, or changes to consent requirements — will be communicated through the consent management platform, which will re-request your consent as appropriate. We encourage you to review this policy periodically.
